[cfe-dev] Hello CLang World!

[Zachary Turner via cfe-dev]

On Windows lib files are typically made with a tool called lib which ships
with Visual Studio.  Unlike ar, which outputs .a files, lib outputs .lib
files.

It sounds like perhaps you need to modify the Makefile to not try to use
ar on Windows, but to use lib instead.
